Security door lock with remote control

摘要

An electrically operated, strong, security system comprising a lock with remote control installed in a wall adjacent to a door frame or under a door. The lock comprises at least one rod which extends into the door when the door is closed and in a locked state. In an unlocked state an actuator retracts the rods from the door, back into the door frame or into the floor. The security lock system provides a manual control for the lock inside a house or building along with indicator lights showing the lock status. An emergency DC battery provides power for the security lock if there is a primary power outage. A remote control locks all doors in the house simultaneous that have such a security lock, and the remote control unlocks only the door or doors selected to be unlocked. The underfloor embodiment of the lock comprises mounting an elongated moveable rod within the door whereby the rod extending from the underfloor lock pushes the door rod upward into the top of the door frame thereby securing the door at the top and the bottom.
